When your headset is connected to the Internet (via the Bluetooth connection to your mobile phone or a computer), you can get notification of the availability of an update (and then apply it to your headset). The W&H BeHear app checks for updates automatically when the Auto option is selected for the Headset Update Check in the Application section of the Settings screen. You can also check manually by choosing the Settings option from the bottom menu of the app and then tapping the Update button on the screen.
